NGC 55

NGC 55 is an almost edge on spiral galaxy about 6 million light-years away. It is a member of the Sculptor Galaxy Group. It is approximately 50,000 light-years in diameter.

The seeing on the night was average (2-3 arcsecs). Processing included noise reduction (mostly on the chrominance data) and some wavelet sharpening.
There are a number of background galaxies visible in the full res version.
